Abstract (en)
A multi-segmented planar antenna with a built in ground plane and method of forming the antenna are described. The antenna elements are formed on a layer of first dielectric (34) having conducting material on both the first and second sides of the layer of first dielectric, such as a printed circuit board. Antenna elements are formed on both sides of the layer of first dielectric using selective etching of the conducting material. Two antenna elements (14) are generally rectangular separated by a narrow gap and electrically connected by two shorting strips across the gap. Two antenna elements (36A) are long and narrow wherein the length of each is an integral multiple of a quarter wavelength of the operating frequencies of the antenna. A layer of second dielectric (56) is placed between the layer of first dielectric having the antenna elements and a ground plane (70). The antenna can be fully encapsulated in a plastic encapsulation material. <IMAGE>
